Fast Dry. Mix with dry china paint to a light cream consistency using an oil free tile & palette knife. Thin with water to a thin consistency. With an oil free brush, paint a thin coat. Let dry & paint over with another coat of oil based china paint. When using as a pen medium, use an oil free nib & wipe nib often as it dries in the point. After penwork is dry, oil base painting can be done on top of the penwork without firing between. This medium works great for mixing White Velvet, china painting & mixing Base for Gold for special techniques & textures.
